Background: The data presented here is part of a doctoral project aimed at characterising and comparing arthropod diversity across biotic communities in coastal ecosystems. The present work provides an inventory of the arthropods recorded in two coastal grasslands ecosystems: the Portugal mainland and the Azores. Sampling was conducted on São Miguel Island (Azores Archipelago) as well as in the Sesimbra and Sines regions (Setúbal District, mainland Portugal). Thirty-one plots were set and visited four times, in spring and summer of 2022.
New Information: The specimens collected were sorted and catalogued into a total of 534 arthropod species and morphospecies. In total, 67 species were common to both ecosystems. A total of 13,515 specimens were counted in the two coastal grasslands. We registered three new records for the Azores (in São Miguel Island), all being exotic: (Thumberg, 1822) (Hymenoptera, Ichneumonidae), , Van Duzee, 1915 (Hemiptera, Cicadellidae) and sp. Patton, 1880 (Hymenoptera, Sphecidae). This publication demonstrates the importance of coastal grasslands as reservoirs for some potentially invasive arthropod species.

Atmospheric deposition of nitrogen and sulfur, after land use change, is one of the most impactful stressors to terrestrial biodiversity. Deposition effects on ecosystems are pervasive, impacting species distributions and disrupting natural communities and associated ecosystem services. Decision makers in particular areas have in the past been limited to using critical loads from faraway research sites or from networks of plots that may or may not overlap with or represent their particular management area.

The joint effects of simultaneous warming and precipitation shifts on soil organic carbon (SOC)-the largest terrestrial carbon pool-remain poorly understood across large spatial extents. By evaluating a global dataset of SOC measurements in the top meter of soil through a space-for-change substitution approach, we show that, averaging across the globe, increased precipitation compensates for warming-induced SOC reductions regardless of soil depth and vice versa. Although additive effects between these two factors are predominant, negative interactive effects, which exacerbate SOC losses, are also common, particularly in tropical and subtropical grasslands/savannas and Mediterranean/montane shrublands.

Fractional Vegetation Cover (FVC) and Land Surface Temperature (LST) are critical indicators for assessing grassland ecosystems. Based on global remote sensing data for FVC and LST from 2001 to 2022, this study employs the Mann-Kendall trend test and Spearman correlation analysis to explore the dynamic changes in and spatial distribution patterns of both variables. The results indicate that the FVC is increasing in regions such as Europe, the eastern southern Sahara, western India, eastern South America, western and southern North America, and central China.
